Digging Out the PPP Hypothesis: an Integrated Empirical Coverage [PDF]
We use several popular tests to test the validity of the Purchasing Power Parity (PPP) hypothesis. In particular, we analyze four classes of tests { standard univariate unit root tests, co-integration, panel unit root tests and unit root tests for ...

An integer ambiguity clustering estimator for real-time precise point positioning
Geo-spatial Information ScienceReal-time precise point positioning with ambiguity resolution (PPP-AR) is considered a valuable positioning tool applicable in various fields. Limited by the precision and stability of real-time satellite products and observation streams, it is ...

Purchasing Power Parity in an Emerging Market Economy: A Long-Span Study for Chile. [PDF]
Recent research has found evidence that supports the purchasing power parity (PPP) condition in developed countries using very long-span data, while evidence for developing countries is almost nonexistent. This paper tries to fulfill this void by testing

Acceleration of PPP Integer Ambiguity Resolution When Emploing Ionospheric Delays
Precise Point Positioning (PPP) is a powerful method for GNSS data processing, when observations from only one receiver are utilized. Since any systematic error is not eliminated by between-stations differencing, introduced precise products and models ...

On PPP, Unit Roots and Panels [PDF]
This paper re-assesses the panel (unit root test) evidence for PPP on four monthly data sets. We discuss and illustrate that commonly-used first generation panel unit root tests are inappropriate for PPP analysis since they are constructed for cross ...

Does PPP hold for Big Mac price or consumer price index? Evidence from panel cointegration [PDF]
This paper examines the validity of purchasing power parity (PPP) using CPI and Big Mac prices. The benchmark model, i.e., the OLS method, which does not take nonstationarity into account, rejects the hypothesis of PPP regardless of prices used.
